Patent number: 10940625Abstract: A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.Type: GrantFiled: April 27, 2018Date of Patent: March 9, 2021Assignee: EHC CANADA, INC.Inventors: Andrew Oliver Kenny, Douglas James Weatherall, Viqar Haider, Ronald Harold Ball, Alexander Stuart Caunce, Reginald Anthony Butwell

Patent number: 10350807Abstract: A method of and apparatus for extruding an article of uniform cross-section, the article including a thermoplastic material and at least one cable for inhibiting stretch of the article. The cable is supplied to a respective tube and is conveyed between upstream and downstream ends. The thermoplastic material may be supplied to the downstream end of the tube. The thermoplastic material is brought together with the cable to embed the cable within the thermoplastic material, thereby forming a composite extrudate. The tube is configured to at least hinder movement of loose windings of the cable from the downstream end towards the upstream end, which may prevent or at least reduce incidence of “birdcaging”.Type: GrantFiled: June 17, 2016Date of Patent: July 16, 2019Assignee: EHC CANADA, INC.Inventors: Andrew Oliver Kenny, Douglas James Weatherall, Viqar Haider, Ronald Harold Ball, Alexander Stuart Caunce, Reginald Anthony Butwell

Patent number: 8820511Abstract: Modified handrails for use in escalators, moving walkways and other transportation apparatus are provided. Handrail can include a configuration for a cable array as a stretch inhibitor that reduces cable buckling under severe flexing conditions. Handrail can also include a configuration for first and second thermoplastic layers in the lip portions that reduces strain and bending stresses and increases fatigue failure life under cyclic loading conditions. Handrail can also include, for the stretch inhibitor, the use of cables comprising large outer strands and small inner strands that enable penetration and adhesion within the first layer and can reduce incidence of fretting or corrosion.Type: GrantFiled: September 10, 2008Date of Patent: September 2, 2014Assignee: EHC Canada, Inc.Inventors: Viqar Haider, Andrew Oliver Kenny, Alexander Stuart Caunce

Patent number: 8323544Abstract: A method and apparatus for pretreatment of slider layer for extruded handrails has a slider layer source, a means of conveying the slider layer to a heating module which subjects the slider layer to an elevated temperature for a residence time, and a means of conveying the slider layer to an extrusion die head. One or more control feeders may be implemented for maintaining portions of the slider layer in a substantially tension-free loop as the slider layer is conveyed from the slider layer source to the extrusion die head. A cooling zone may be included to ensure adequate cooling between the heating module and the extrusion die head. Means for reducing heat transfer between the extrusion die head and the slider layer is also provided.Type: GrantFiled: September 10, 2008Date of Patent: December 4, 2012Assignee: EHC Canada, Inc.Inventors: Viqar Haider, Andrew Oliver Kenny

Publication number: 20070284031Abstract: A film and a method of applying the film to a handrail of an escalator or moving walkway are provided. The film can be a single or double layered film. Printed matter, e.g. advertising, can be applied to or between the films. An apparatus and related method for applying the film are also included and rely on the motion of the handrail to unroll a supply of the film, with one or more rollers pressing the film onto the handrail. The film is stretched during application to prestretch and reduce tendency for compressive strains in use to cause wrinkling of the film and detachment from the handrail. To retain the ends of the film in relative position, a film cap is fused or bonded to end portions of the film.Type: ApplicationFiled: July 5, 2007Publication date: December 13, 2007Inventors: John McLeod, Viqar Haider, Ion-Viorel Tatu
